ISOCAM images at 6 . 75 μ m and 15 μ m : the circumnuclear region of NGC 4321 ( M 100 ) ⋆
We present ISOCAM images (1.5 ′′ px −1) in the LW2 (6.75 µm) and LW3 (15 µm) broad band filters of the circumnuclear starburst of NGC 4321 (M 100). A detailed comparison with the emission at other wavelengths (U , B, Hα, and CO) is also presented. The nature and intensity of the mid-infrared emission is shown to be remarkably different from one star forming region to the next. For instance, sta...
متن کاملThe obscured circumnuclear region of the outflow galaxy NGC 3079
Images of the central region of the almost edge-on Sc galaxy NGC 3079 in the J , H and K-bands and in the v = 1→0 S(1) line of molecular hydrogen are presented. The inner few kiloparsecs of NGC 3079 exhibit a large range of nearinfrared colours caused by varying contributions from direct and scattered stellar light, emission from hot dust and extinction gradients. Our results show that interpre...
متن کاملImaging the Circumnuclear Region of NGC 1365 with Chandra
We present the first Chandra/ACIS imaging study of the circumnuclear region of the nearby Seyfert galaxy NGC 1365. The X-ray emission is resolved into point-like sources and complex, extended emission. The X-ray morphology of the extended emission shows a biconical soft X-ray emission region extending ∼5 kpc in projection from the nucleus, coincident with the high excitation outflow cones seen ...
متن کاملKennicutt-Schmidt Law in the Central Region of NGC 4321 as Seen by ALMA
We present the Atacama Large Millimeter/Sub-millimeter Array (ALMA) cycle-0 science verification data of the CO(1-0) line emission in the central region of NGC 4321 (also known as M100) at the distance of 17.1 Mpc and VLA, L-band data of HI of the same galaxy. We have drawn the center area of M100 in the (12)CO(J = 1-0) line with the resolution of (3.87″ × 2.53″) as viewed by ALMA, along with H...
متن کاملA circumnuclear molecular torus in NGC 1365
The central region of NGC 1365 has been mapped in the J = 3 − 2 CO emission line with the 15 m SEST, which has a HPBW of 15′′ at the frequency of this transition. The observing grid has a 5′′-spacing in the inner and a 10′′-spacing in the outer region. A deconvolved map has been produced using the Maximum Entropy Method (MEM). A circumnuclear molecular torus with a radius of about 6. ′′5 is the...
